Editing Game state

There are two '''game states''' during the [[Duel]], "open" and "closed".

Whenever a player performs an action, the game state is "closed". If nothing is going on, and neither player wishes to do anything, the game state is "open". Technically, this means:
# The [[Turn Player]] has the chance to activate the next [[fast effect]]
# The turn player passes to the opponent
# The opponent then passes back
# No [[Chain]] is currently being formed
The game state is "open".

If the game state is "open", the [[turn player]] may perform any of the following actions, when appropriate:
*Conduct their [[normal draw]] (during the [[Draw Phase]])
*[[Normal Summon]] / [[Set]]
*[[Flip Summon]]
*[[Special Summon]] (That does not start a [[Chain]])
**[[Synchro Summon]]
**[[Xyz Summon]]
**[[Pendulum Summon]]
**[[Link Summon]]
*[[Battle Position changes|Change a monster's battle position]]
*Attempt to move to the next [[Phase]]/Step
*[[Declare]] an [[attack]] (during the [[Battle Step]] of the [[Battle Phase]])
*[[Activate]] any card/effect of any [[Spell Speed]].

If the game state is "closed", then only [[fast effect]]s can be activated, dependent on [[Fast Effect Timing]] rules.

Any wrong action or error in play will break the game state; whether or not the game state can be repaired can mean the difference between a [[Warning]] and a [[Game Loss]].
